@mattyglesias I think this is only looking at one half of an arms race. The other half is that you'll have AI agents working as buyers for your household. They can get on Tor or whatever it takes, they can order stuff in advance, they can arbitrage in crazy ways. It will be easy for them.

Ubiquitous price discrimination is going to be extremely annoying, especially for relatively affluent people who are also lazy and inattentive (ie me personally) Possibly good for the poor, who will be internalizing their own thriftiness more. slowboring.com/p/the-racial-j…

@CarlOrkmansen Penicillin 1928. Polio vaccine 1955. Measles vaccine 1963. I grew up eating only fruits and vegetables that were in season. My dad was never on a plane in his life.

Been at ESPN a long time - this one was an all timer. Before social media, it was as viral as a story can be. I watched it on a tape in the news room. I couldn’t stop watching his teammates.
Dr. Lemma@DoctorLemma

19 years ago, a high school basketball coach put his team manager into a game for the final four minutes. The kid had never played a single minute of competitive basketball in his life. He scored 20 points. Jason McElwain was diagnosed with severe autism at age two. He didn’t speak until he was five. He couldn’t chew solid food until he was six. He wore a nappy for most of his early childhood. As a baby, he was rigid, wouldn’t make eye contact, and hid in corners away from other children. He tried out for his school basketball team every year and got cut every time. Too small. Too slight. Barely 5’6 and about 54 kilograms. But he loved the game so much that his mum called the school and asked if there was any way he could be involved. The coach created a team manager role for him. For three years, McElwain showed up to every practice and every game. He wore a shirt and tie on match days. He ran drills, handed out water, kept stats, and cheered every basket like he’d scored it himself. On 15 February 2006, the last home game of his final school year, the coach let him suit up in a proper jersey and sit on the bench. With four minutes left and a comfortable lead, the coach sent him in. His first shot missed. His second missed. Then something shifted. He hit a three-pointer. Then another. Then another. His teammates stopped shooting entirely and just kept passing him the ball. He hit six three-pointers and a two-pointer. 20 points in four minutes. The highest scorer in the game. When the final buzzer went, the entire crowd rushed the court and lifted him onto their shoulders. His mum tapped the coach on the shoulder, in tears. “This is the nicest gift you could have ever given my son.” McElwain won the ESPY Award for Best Moment in Sports that year, beating out some of the biggest names in professional sport. He’s 36 now. He works at a local supermarket, coaches basketball, has run 17 marathons including five Boston Marathons, and travels the country speaking about never giving up. When asked about that night, his coach still gets emotional. “For him to come in and seize the moment like he did was certainly more than I ever expected. I was an emotional wreck.”

Pretty compelling piece in al-Jazeera (!) today arguing that the U.S.-Israeli plan is working quite well: Trump has degraded Iran militarily, proxies are fragmenting, Strait of Hormuz pain being most felt by China, etc. Actually quite convincing. Curious for the dissents.

One very weird thing about having done _just enough_ coding is that I can usually understand when Claude Code explains to me the cause of the bug I have, even though I didn't really generate that hypothesis myself. (It was a race condition in concurrent processes. Of course.)

@esterdiol @KelseyTuoc @brazen__head If you asked me "when was the US child mortality rate 10x higher than it is today?" my first guess would've been like 1776 or something. It turns out the answer is 1940.

I doubt that anyone I know steals from Whole Foods, but the milieu that the article depicted, where it's normal for perfectly well-off people to steal things because why not, was really upsetting to read about, so I actually want to try to earnestly explain why you shouldn't do this just in case there's someone out there who has never had it explained to them. When a business opens - or really, as soon as a business starts making plans to open - a defining question for the business is how it will collect payment for the goods or services it provides. If you trust the people you sell to, you can be pretty relaxed about this; send people an invoice, most of them will pay it on time, any who don't will pay it a bit late. You have to think about convenience and mistakes but not about people trying to cheat you. This saves you so, so much defensive planning to make sure you get paid. It's so much easier. But if you're selling to the general public, you do have to think about people trying to cheat you. You have to structure the physical store so that it's hard for them to steal. You have to not carry some items that you'd like to sell, because they'd also be attractive targets to steal. If people swap price tags between items, you can't use stickers. If people put things on in the dressing room and wear them out, you need to pay someone a full time salary to monitor the dressing room. The world that we all live in is much poorer than the world we'd live in if people didn't steal. The stores don't carry things that they could carry if people didn't steal. They don't use pricing and inventory systems that would be way easier and more convenient if people didn't steal. But it could be much worse! If I walk down to my local Whole Foods today, items on the shelves won't be locked behind sheafs of plastic - that is only worth it when the background rate of stealing is much higher than it is at my local Whole Foods. When more people steal, businesses have to further intensify security, or go out of business. When you shoplift, you directly and unambiguously impoverish your community. You make prices higher for everybody else, you make stores less usable for everybody else, or you make businesses not viable that would otherwise be viable. The direct impact each time is small, but it's a lot larger than the direct impact of taking some trash out of the trash can to throw on the ground, or pouring just a tiny bit of poison into your local river, and most people have a deep, instinctive abhorrence of antisocially wrecking your community like that. So don't steal. The other thing that it seems possible some people might not understand is that while you might have a social circle that is incredibly nihilistic and cynical and thinks that everybody steals, in fact this is not true. Most people do not steal. Most people, if they learn that you steal, will lose more respect for you than you had to lose. I don't know anyone who has shoplifted except 'as a kid/teenager'. It is not always the case that virtue is rewarded and vice is punished but even before you bring the legal system into it, the risk-reward tradeoff of having everybody you know know that you steal things sometimes is absolutely terrible. Who would hire someone who steals things? Who would trust them around a vulnerable person? Who would want to live in a society with someone who will delightedly and routinely wreck it for the slightest personal benefit? I hope that "Gina" turns her life around. I hope that Gina realizes that she needs to. And if you have been told that it's just a corporation or that having ethics is lame or that if you think about it, other bad things happen too, like wage theft, so that means stealing is okay, I hope you really, actually, think about whether you'd accept any of those as excuses for anything else.
@

People hate the tone of this piece, but my view is you don't need a journalist to tell you wrong things are wrong. (She does also call her thieving friends nihilists.) It's weird to be surrounded by thieves though -- if people I know steal from Whole Foods, they don't admit it.

@zooko Correction: there's an experimental/nightly-only feature in Cargo that uses BLAKE3, but I don't think most Rust users running the stable toolchain are touching BLAKE3 at all. Someday!

Are you aware of uses of the BLAKE3 secure hash function? Please contribute to this list! bfswa.substack.com/p/where-is-bla… My hope is that lots of different tools all using the same secure hash function can result in “accidental” opportunities to protect and empower users.

@EUhobgoblin @waitingout23672 @0xVKTR Maybe more to the point, each economist enjoyed watching the other guy eat shit more than he disliked eating shit himself. They could've just traded eating shit directly and reduced transaction costs. But they didn't know that up front, and prices carry information.

@LeahLibresco Theoretical waffle packing is stuck in its ivory tower, out of touch with the needs of the common man. Applied waffle packing solved this in the 90's.

In 2002 they ran a study on trying to quantify just how much medical technology is responsible for the murder rate dropping and what they found was Murder rates would be 5x higher. Medical Technology actually masks violent crime epidemics.

This was one of the main reasons we set out to create BLAKE3 about seven years ago—to finally replace MD5 so that people could be more secure. That is still a work in progress!
Oseni Solomon@ForenX_Intel

We've been loyal to SHA-256 and MD5 for so long it almost feels wrong to question them. But loyalty doesn't scale when you're staring down terabytes of data files to hash during traige. That's where BLAKE3 comes in and brother, this thing is not joking.

@KelseyTuoc @notjessewalker I wonder if there's a baseline sense of "I'm not gonna stoop to their level" that we all share, even when we point it at each other. But if we immerse ourselves in (what we perceive to be) our opponents' vile lies all day every day, something breaks and we stop trying?

@notjessewalker I assume what is happening here is that they've built a culture that's corrupt and dishonest from top to bottom, so the people making statements have no way of even learning what's true and therefore what will come back to bite them.

I don't expect the folks running DHS to say "Maybe we shouldn't lie all the time," because the folks running DHS are morally rotten people. But you'd think at some point someone might say, "Could we come up with some lies that don't unravel within 24 hours?"
Sam Stein@samstein

DHS spent today replying to individual tweets saying they left this man in a coffee shop "determined to be a warm, safe location" only for video to emerge tonight showing it was the middle of the night, cold and the coffee shop was closed.

@rudie_cantfail @gnrtvty @slatestarcodex @KTmBoyle Eh one of the reasons social norms get shattered on the internet is that it's ambiguous whether you're talking to a small group or a big group. It's even different to different observers. I might see some random comment right under the famous person, and you might see it buried.

@gnrtvty @slatestarcodex @KTmBoyle You blocked me, but I'm sure you'll unhide to read this: walking over to where people are talking and loudly yelling "I don't get what this is about! You're rude! Explain!" is anti-social behavior. Research the context or not, it's up to you, that's not really the issue here.

@johnvmcdonnell @bryan_caplan Honestly I think politics would be a lot healthier if most people's default framing was "our ideas are not popular (yet)" as opposed to "everyone loves our ideas, but [villains] are holding us back".

If any good idea is "politically impossible," ask yourself, "Who makes it impossible?" And if you're going to be angry at anyone, be angry at them.
